Checking drive ordering between SL3000 and SAM

preparation

1. Shut down sam samd stop
2. ensure all drives are clear (SLConsole)
3. find out which tape drives are defined in Solaris

   ls -l /dev/rmt/*[0-9] | awk '{print $9, $10, $11}'
   /dev/rmt/111 -> ../../devices/pci@78,0/pci8086,e08@3/pci1077,171@0/fp@0,0/tape@w500104f000aedc31,0:

4. Choose tape cartridges for testing, I'll use ti.100090 (2,7,1) and 040990L4 (2,15,1), loading 100090T2 into CAP (can only load from system slots or CAP to drive)
5. Check ordering of drives acording to HLI/SCSI numbers:
6. starting from drive 1 (top of list when sorted by HLI/SCSI address), loading tape into drive, waiting for drive to become ready and check mt on all rmt devices via small loop null test:

   for i in /dev/rmt/*[0-9]; do mt -f $i status; done
   /dev/rmt/111: no tape loaded or drive offline
   /dev/rmt/112: no tape loaded or drive offline
   /dev/rmt/113: no tape loaded or drive offline
   /dev/rmt/211: no tape loaded or drive offline
   /dev/rmt/212: no tape loaded or drive offline
   /dev/rmt/213: no tape loaded or drive offline
   /dev/rmt/311: no tape loaded or drive offline
   /dev/rmt/312: no tape loaded or drive offline
   /dev/rmt/313: no tape loaded or drive offline
   /dev/rmt/411: no tape loaded or drive offline
   /dev/rmt/412: no tape loaded or drive offline
   /dev/rmt/413: no tape loaded or drive offline
   

Example run

1. via SLC load 100090T2 into drive 1,1,2 (recovery move)
2. verify via SLC that drive is in state "loaded" (system detail)
3. verify that tape is loaded correctly via mt

   for i in /dev/rmt/*[0-9]; do mt -f $i status; done
   /dev/rmt/111: no tape loaded or drive offline
   STK     T10000D          tape drive:
      sense key(0x6)= Unit Attention   residual= 0   retries= 0
      file no= 0   block no= 0
   /dev/rmt/113: no tape loaded or drive offline
   /dev/rmt/211: no tape loaded or drive offline
   /dev/rmt/212: no tape loaded or drive offline
   /dev/rmt/213: no tape loaded or drive offline
   /dev/rmt/311: no tape loaded or drive offline
   /dev/rmt/312: no tape loaded or drive offline
   /dev/rmt/313: no tape loaded or drive offline
   /dev/rmt/411: no tape loaded or drive offline
   /dev/rmt/412: no tape loaded or drive offline
   /dev/rmt/413: no tape loaded or drive offline
   

4. or in short:

   for i in /dev/rmt/*[0-9]; do if [[ ! $(mt -f $i status 2>&1) =~ 'no tape loaded or drive offline' ]]; then echo $i; fi; done
   /dev/rmt/112
   

5. unload to CAP, repeat
